Novillo bullfighter Aarón Palacio performs in Pamplona

Young "novillero" bullfighter Aarón Palacio appears to soar through the air as he kills a "novillo" bull from the ranch of Pincha during the first bullfight in Pamplona, northern Spain, within the singular Feria del Toro (Bull Festival) on July 5, 2025. Tomorrow the annual Fiesta de San Fermín begins with the first bull-run on July 7. Photo by Jim Hollander/UPI
